Additional meeting and call-related features and issues within Microsoft Teams for business
I am having the same problem, and it appears to be a systemic problem with Microsoft Teams that has persisted for some time. The large volume of suggestions that require user action and apparently have not worked is unfortunate. Both Google Meet and Zoom are much easier to use and do not require such complicated user actions to fix issues. Those companies appear to resolve reported problems quickly, but maybe they just have fewer issues.
I'll give MS one more shot to fix it, then on to something more user friendly.
